That is just flat out execution. I mean just think of that. Play after play after play after play. Defense has no chance to adjust or substitute. Pure focus, no false starts or procedures. Mr. Kelly is doing something right. UCLA's defense last night was looking all "Errr...What?...Where?...Huh?...."
Every 18 seconds they run a play, when the running back was getting off the ground the linemen were coming up and ready to go. It's amazing, at that tempo the D doesn't have time to shuffle players in and out.
